Mark Hetfield is the CEO and president of HIAS, a pro-refugee group, and he is an outspoken critic of President Donald Trump's travel ban.

Trump's executive order, signed Friday, bars citizens of seven countries from entering the United States for the next 90 days, suspends the admission of all refugees for 120 days and indefinitely suspends the Syrian refugee program.

On "Tucker Carlson Tonight," Hetfield said that the travel ban does not represent "American values."

He argued that we're "turning our back" on refugees, and we have some responsibility to protect people who are fleeing for their lives.

Tucker pointed out that there are more than 60 million refugees worldwide, according to the U.N. He asked how we're supposed to determine what percentage of refugees we have an obligation to help due to our "American values."

"I'll tell you what, it's not zero," Hetfield replied.

Tucker repeatedly pressed him to explain what criteria we can use to determine that.

"If you're going to run around with moral statements like, 'You're a bad person because you're against refugees,' tell me what the rules are, so I can be a good person."
